PLATE PUNCHING AND FINISHING MEANS.

Application `filed July 29, 1926. Serial No. 125,707.

The present invention relates to plate punching and finishing means. a

More particularly the present invention relates to means `for punching a plurality of holes in a plate and reaming the materialV around said holes to remove the rough edges left by thel punching tools.

An object of the present invention is to provide mechanism of the kind referred to Vin which the punching and reaming operations are performed in timed relationship with one another.

A further object is to provide va plate punching and reaming machine which will expeditiously handle plates in which a large number of holes are to be punched and reamed.

A further object is to provide a machine for punching and reaming holesin a plate Which is simple, positive in action and well adapted to meet the requirements of commercial service.

Further objects will appeal' as the description proceeds.

The present invention is particularly useful in punching .and reaming the holes in plates designed for forming the cylindrical walls of washing machine cylinders.V Such plates are provided with a large number of holes for permitting the ingress and egress of washing medium while retaining the.

goods to be washed. According to the present invention, a flat plate to be operated upon is clamped in posi-tion and punches 'are operated to punch one or more rows of holes at a single operation. The punching operation ordinarily leaves a burr, land the present invention contemplates reaming means operated in predetermined relationship with the punchingmeans for removing` the burr from the various holes left from such a punching operation. The plate to be operated upon is fed through the machine with a step-by-step movement, the holes being l punched one or more rows at a time and being advancedinto position to be operated upon the reamers. y

Referring first to Figure 1, the numeral 10 indicatesv the bottom die of a unch, the

upper or movable die 'being omitted from said gure for purposes `of clarity. The numerals ll-.lliindicate a pair of guideways adapted to slidably` receive a pair of plate clamping members 12.-12. As illustrated in Figure 5, each of the plate lclamping members 12 is provided with a recess 13 adapted to receive the side edge of a plate 14 The cap `screw 15 is provided for firmly gripping the adjacent side' Eedge ofthe plate 14. Each of ,the plate clamping members 12 is provided on its under side with the removable rack 16, which rack forms part of the step-by-step mechanism by means of which the plate 14 may beadvanced witha step-by-step movement through the machine.

By reference to Figure 3 it will be noted that the punches 17 ,-17 carried by the block 18 are disposed in position to cooperate with the stationary die 10. Said vblock 18 is carried by the .operating member 19, which may be .driven from vany preferred source of power (notsliown)- Also carried by the Op' l vided near its lower extremity with the cam-V ming 'surface 212 .adapted .to cooperate with the abutment 23 ,carried by the reciprocating said plate 24 "(Figure 9). Said reciprocating plate 24 is urged in a right-hand direction as the parts are viewed in Figures 4 Vand 9 by the spring 25. Pivotally mounted upon plate 24 is the dog or pawl 26, which is weighted by means of the ball 27 to non mally occupy a position in engagement with the rack 16. 1t will be obvious from an inspection of Figure 9 that an upward movement of the camming bar 21, which is to say an upward movement of the operating member 19, will move the plate 24 in a lefthand direction as the parts are viewed in Figures 4 and 9, wherebv the dog or pawl 26 will move the cooperating rack 1G one step toward the left. As the operating member 19V and the camming bar 21 descend, the camming surface 22 of the camming bar 21 will be moved out of engagement with the abutment 23, and the spring 25 willdicated in Figure 1, the spindles S-3() are arranged in two parallel rows. The gears 31 at the lower extremities of the spindles in each row are connected in a train in the manner indicated in Figure 7 being driven by the common gear 32. Said gear 32 is driven by the gear 33. The gears 31-31 .and gear 32 move up and down with the block 29. The (Year 32 1s driven b the fear t: y D

33,\which according to the illustrated embodimentof the present invention does not have an axial movement. In order topermit movement of gears 30-31 and gear 32 relative to gear 33, said gear 33 is made relatively wide, in order to avoid the demeshing of gear 32 from gear 33. The gear 33 may be driven by the gear` 34, which gear V34 may be'driven by the pulley 35.

Each of the spindles 30 is provided at its upper extremity with a reaming tool 36. In order to permit the ready insertion and withdrawal of the reaming tools 36, each of said tools 36 is provided with a shank 37 having an annular groove 38 adapted to receive the spring-pressed ball 39, It will be obvious that, by means of4 the construction illustrated, each of the reaming tools 536-36 is removably held within its corresponding spindle 30. The lower extremity of-each of the spindles 37 may be non-circularlin cross section, fitting into a smaller' hole in the spindle 30, whereby rotary movement of the spindles 30 will be communicated to the reaming tools 36.

From an inspection of Figure 8 it will be noted that the-reamer block 29 is pivotally supported' by means of the yoke 40, which yoke is pivoted upon the relatively fixed lugs 41-41. The hars 28-28 are positioned to cngagewith the yoke 40 when the operating member 19 is depressed. Lowering of the operating member 19 will therefore not only accomplish the punching operation by the punches 17-17, but will cause the rocking of the `yoke 40 to lift the reamer block 29. The result will therefore be accomplished that a row or rows of holes will be punched, and at substantially the same time a row or rows of holes previously punched will be reamed. Y Y

The numeral 42 indicates a lever pivoted for movement about the pivot 43, which lever 42 is connected by means of the link 44 to thc middle of the yoke 40. By depressing the free extremity of the lever 41, the operative may lift the block 29 independently of the operating member 19, thereby accomplishing a roaming operation' entirel Vindependently of the punching operation, i i such a reaming operation should be considered to be neces-` sary.

The mode of operation of the above describedembodiment of the resent invention will be clear without detailed explanation. It may he stated briefly, however, that when itis desired to punch and ream a plurality of holes in a plate, said plate will be clamped with its side edges disposed within the clamping members 12-12 at the two sides of the machine.` When said late has been properly positioned for the rst punching operation, the operating member 19 will be lowered through mechanism not shown,

whereby the punches 17-17 inv cooperation with the die member 10 will punch a plurality of holes, `When the operating member 19 is in its lower or punching position, the camming surface 22 of the camming bar 21 will of course be in lowered position, whereby the spring 25 may draw the abutment 23 to the right as the parts are viewed in Figures 3, 4 and 9, permitting the pawl or dog 26 to engage with the next successive tooth on each of the racks 16. When the operating member 19 is again raised, the camming surface 22 will move the abutment 23, plate 24 and pawl or dog 26 to the left as the parts are' viewed in Figures 3, 4 and 9, resulting in movement of the plate 14 toward the left. After one or more punching operations have been performed, holes previously punched in the plate 14 will be ositioned over the reaming tools B6-36. i ach time the operating member 19 is depressed, the operating bars 28-28 thereof willengagethe yoke 14 i to cause the lifting of the reamer block 29.

Inasmuch as the reaming tools 36*36 are being continuously rotated, the result Will be accomplished that at each downward movement of the operating member 19, not only will a punching operation be performed, but the reamer block 29 Will be raised to perform reaming functions on holes previously punched.

Though a preferred embodiment of the present invention has been described in detail, it will be clear that many modifications will occur to those skilled in the art. It is intended to cover all such modifications that fall Within the scope of the appended claim.

That is claimed is:

In punching and reaming mechanism, in combination, plate holding means, means for advancing said holding means With a stepby-step. motion, punching means, a reamer block carrying a plurality of reamers, means for rotating said reamers, means for pivotally mounting said reamer block, means operating in synchronism With said punching means for moving said reamer block to bring said reamers into operative relationship with holes previously punched by said punching means, and means for moving said reamer block into operative position independently of said punching means.
